How to fix the Airtel SIM card not working issue?
Now that we understand why the Airtel SIM isn’t working, let’s quickly discuss the fixes.
Restart your phone
This is probably the easiest fix you can try. Restarting the device clears the RAM of corrupt files and minor bugs, which may help you fix the issue.
Reinsert the SIM card

The second step is to remove the SIM and reinsert it in the slot.
Ensure that the SIM card is inserted properly with the right side up. You can read your device’s manual for more information. Also, do not use a pin or another instrument to open the SIM tray. Only use the designated SIM tray opener provided with your mobile.
Activate SIM
Usually, SIM services are activated the moment you insert them into the mobile. However, sometimes, you will have to call customer care if your SIM has not been activated in 24 hours.
Check network settings
To use the Airtel SIM, you must tweak your device’s network settings. Read the manual that comes with the SIM card for the correct network settings. You can also contact Airtel customer support for more technical and detailed help.
In conclusion, Airtel SIMs may not work due to activation issues, network outages, physical damage to the SIM, incompatible devices, or incorrect network settings. To fix the issue, start by restarting your device and then follow the steps until you have resolved it.
